' to provide both battery and magneto for the.

ignition, the high tension current being ourried from the distributer to the respective spark-plugs by well'insulsted-wires,and in some cases svitclzes are used at the plugs for the purpose of conveniently cutting out one or severol of the cylinders in making when the motor is running with-any of these switches open, there being no outlet for-the high tension current, the voltage tends to build up to such an extent that there is.

danger of breaking downthe insulation in the trasformer coils or other ports of the high tension circuit, In srranging the ignition cirtfuit-s one side of each circuit is usu silly grounded on the motor frame and cylinders, and in the present invention, in

order to avoid the danger of breaking down the insulation when any of the switches are open, 1 have provided means for grounding the switches on the motor cylinder when they are moved from-contact with their respective spark plugs. In combination with T the means for grounding the switches i' have provided a nest and substantial hous ing forthe ignition wires and-support for" ..Other 'dsjeets'jane the features of novelty ofths intention will be appsreritfrom the following Ygicscription taken in. connection with the accompanying drawings.

so the switches and contact or grounding dc? tion-circuit condui g It has been foundthatv In the drawings, lugure '1 1s a sideelevs section of the motor crank case upon which sire mounted the cylinders 11., these cylinders being preferably cost in. pairs, as shown 111 l 1g. 1. The motor, which is preferably oi the wutcrcoolcd type, is "provided with :1 80 ischz rge water conduit 12, which is 2H- -rangeC centrally above the cylinders and communicates with the jackets thereof by neans of suitable branches 13, one of which s clesrly shown at the right side of Fig. 1.' lhesnlet and exhaust ports for the motor are preferably. orrsngedon one side thereof and communicate Withthc interior of the cylinder by means of passages arranged {it the top of the cylinders and into which 7 spark plugs project... Bosses'or lugs ll are arranpcd-on the side of the water conduit 12 toward the spark plugs and :iu'igniitlon circuit conduit comprising the booking member 15 and the i'ucing'uieinbcior Wirmg board 16, are arranged on these bosses or lugsv Suits le switches 17 ure'mounted on the frontside'o'f the facing member 16. inlx'nc with the spark plugs of each pair of cylii'ldcrs, as cleorly shown in Fig. 1. 1 These 0 switches are preferably arranged to have llIl1 \'6lS&ll movement and are secured to the incing member by means of suitublescreus 18 which engage nuts 19 embedded infthe rectangular recesses 20 in the rear side of 35 the facing member 16. in order to prevent. the switches from turning on the screws 18. suitable dowel pins 21 are provided. The backing member 15 of the ignition circuit conduit is preferably made of wood or other insulating material and of U-shaped cross section and provided with upward extort s1ons22, through which the bolts 23 are passed. As will be seen from Fig. 2, the front side of the backing member 15 lSllOl- .95 lowed out receives the facing member 16,111 the rear side of which are formed suitable grooves for the ignition circuits. Y

As shown i-n'Fig. l, the magneto 24 is arranged at one side of the motor and driven by means .of eshaft 25. The magneto is provided with the usual distributor 26 for distributing theiignition current to the various cylinders inproper sequence and the various conductors which connect with the 1025 magneto and the distributor puss upwardly. through the insulating tube 27 and through suitable open u 's 28 in thefsciug member In order to secure the ignition circuit conduit against the bosses 11 and also provide moans for short-circuiting the circuits when the switches are not connected with the spark plugs, clips or brackets 29 are provi (led. 'lhcse clips or brackets are provided with a downwardly extending portion 30 which engages the face of the ignition circuit conduit and is secured thereto by means of a suitable screw 31 which extends through the facing member 16 and engages a nutmounted in the rear of the latter in a manner similar to the arrangement of the nut 19 above described. The clip or bracket 29 is.

also provided at the top with a lateral ex tension 32, which overlies the extension 22 on the backing member 15 and has its end in engagement with the lug 14. The bolt 23 passes through the lug 14, the extension 22 and the clip 29, and is provided on the front side ofthe latter with a nut 33, by means of which the extension 32 on the bracket is drawn against the lug 14: and the lower portion 30 of the bracket clamped against the face of the ignition circuit conduit so as to hold the latter against the boss or lug 14.

The brackets 29 are also provided with ex- On account of the arms 35 being arrangeddirectly above the spark plugs, it will be seen that the switches may be quickly thrown from contact with the spark plugs to the arms by an upward movement. By providing a universal movement for the switches any disalinement of the arms and spark plugs wilLnot interfere with the operation of the switches.

Referring to Fig. 5, in which the wiring diagram or the ignition system is shown, 36 indicates the storage battery for supplying the ignition current when the magneto is not in use. The currents generated by the ma gneto and by the battery are brought to the usual switch 37 by means of which either the battery or the magneto may be thrown into service. From the switch 37 the current is passed through the usual induction coil and from the latter the high tension current is carried by means of the Wire 38 to the distributor 39, by which it is distributed to the cylinders of the motor through the circuits *0, one of which is showncomplete. The wires 4-0 are brought through the insulating tube 27 and the openings 28 in the wiring board and arranged in the grooves 41, 42,43,

14-, 45 and 46, from which they pass through openings -17 to the front of the wiring board and connect with. the various switches. When the switches are in contact with the spark plugs the current passes through the switch and across the gap of the spark plug and to the ground. W hen the switches are in contact with the arms 35, as shown in dotted lines in Fig. 2, the current will pass through the switches to these arms and from the latter through the lugs 14 to the ground. The low tension wires leading from the magneto to the switch and coil 37, which is usually located on the dash-board of the vehicle, are carried through the tube 27 and the groove 48 in the back of the wiring board.

It will be seen that the above-described arrangement of the ignition circuits provides for their complete insulation and produces a simple and neat appearance and the wires are so located that they are not liable to be injured in any way. By providing the clips or brackets 29, which carry the arms 35,1 have produced a construction which is simple and effective in operation and serves the double purpose of securing the ignition circuit conduit in position and providing a means for grounding the ignition circuits, when they are not closed, through the spark plugs.
